Matching reco to MC truth [Andrew Furmanski]
-
mccheat::BackTracker
uses fixed metrics and a single algorithm for matching generated and reconstructed objects
-
revamping
MCTruthMatching
to perform this task
-
currently that module abuses an existing data product,
anab::T0
, to store the result
-
[Jason Stock] is this module performing truth matching to optical reconstructed objects too? [A] No; the meaning of that would need to be thought [Jason Stock] DUNE is working to such matching, it might make sense to coordinate
-
[Jason Stock] is in the process of reworking
BackTracker
; this use case may be important to determine which direction to take
-
[Robert Kutschke] is this scheme admitting a many-to-many association? [A] Not at the moment [Erica] That needs to be discussed
-
[Robert Kutschke] two recommendations: use enumerators instead of strings; use a specific structure instead of a pair
-
[Wesley Ketchum] use a specific structure including explicitly what needed, instead of a generic list of pairs; that one can be extended later
-
[Erica Snider] the use of
anab::T0
as a box to store truth matching should be deprecated
Conclusions
-
the old "special" behaviour of
anab::T0
will be deprecated
-
after the suggested changes, a first version of the module will eb pushed, possibly this very week
-
discussion will follow on the possibility of having multiple MC particles associated to a reconstructed object
Release and project report [Erica Snider]
-
art 2.8 is out, including the possibility to process input files with a different art "history"
-
declaring the products used ("consumed") is a new optional feature helping parallelisation
-
lar::PtrMaker
has been adopted from LArSoft into art::PtrMaker
-
the coming LArSoft release will not include the new art 2.8
